The Ultra Zone brings the new EnMotion reactive coverstock from the Twisted Fury into the Zone line and combines it with the updated Phantom core to create an ultra-low-RG alternative that complements the reaction of the Twisted Fury. The Ultra Zone uses a Solid / Pearl Hybrid version of the EnMotion coverstock. EnMotion combines the best elements from our PowerKoil, Activator and N’Control coverstock systems to create good length combined with excellent mid-lane recovery and strong back-end hooking action. The Ultra Zone unites EnMotion coverstock with the ultra-low-RG updated Phantom core. Ultra-low-RG’s are known for strong mid-lane recovery moves and their controllable back-end hooking action, Brunswick has created an early revving counterpart to the Twisted Fury that will match-up better on lane patterns that create over/under reaction problems for skid/snap balls.
